CABLE STOP FOR TRAVELING CARRIERS.

Application filed February This invention relates to a stop for traveling carriers of the type commonly used for transporting hay, ensilage, litter and other materials to or from a barn, and having rollers to operate on a cable or a'connected track and cable leading from within the barn 'to a convenient point for loading or unload- The stop of the present invention is de signed to enable the positive holding of the carrier at any point along the length of its travel against drifting movement in either direction to avoid the annoyance and inconvenience commonly met with, due to a sagging of the cable.

The principal feature of the present invention is the provision of a stop for the purpose referred to, which may be applied to practically any type of carrier and is arranged to be suspended freely therefrom when not in use, and may be placed into position on either .side of one of the support ing rollers of the carrier to have the roller roll upon and rest on the device along-side an abutment provided thereon for holding the roller against movement.

The invention is more fully described hereinafter .and is illustratedin the accompanying drawing in which Fig. l is a side view of .a litter carrier or other similar traveling carrier operating on a cable and equipped with a cable stop in accordance with my invention;

2 is a perspective view of the cable stop detached from the carrier, more clearly to disclose the form thereof; and

Fig. 3 is a fragmentary vertical sectional detail to illustrate the operation of the stop.

The same reference numerals are applied to the parts in all three views.

The carrier 5 comprises the usual basket or bucket 6 and suspension frame 7 having brackets 8 extending therefrom and provicing mountings for sheave rollers 9 to opcrate on a cable 10. The latter usually extends from a point within the barn or other enclosure from which or into which the material to be transport-ed is to be taken and leads out to some other point remote from the barn where the material is to be unloaded or loaded, as the case may be. Usually some form of trip device is provided at the remote end of the cable to unload the contents of the carrier when it arrives at its destination where the carrier, for example, is used for transporting litter, trash or other 10, 1926-.

refuse from a barn. In some instances, a span of overhead track is, provided within the barn .and the cable is connected therewith in a manner permitting the riding of the carrier from one onto the other. In many instances, however, the cable extends the entire length of the travel of the carrier.

Considerable inconvenience and annoyance has resulted in the operating of traveling carriers of the type above described due to a sagging of the cable which resulted in the drifting movement of the. carrier away from a position in which it was desired to keep the same as, for example, when loading. In some instances, where litter to be loaded into the carrier is collected at different points in the barn and the carrier is brought from pointto point, it used to be necessary either to hold the carrier in place or provide some makeshift to prevent its movement during loading. According to the present invention, I provide a stop 11 which may be permanently attached, suitably to one of the brackets 8, by means of a chain or other form of flexible connection to be placed on the cable on either side of one of the roll ers 9 to hold the carrier from movement in whichever direction it intends to drift. The permanent attachment of the stop to the carrier in the manner shown insures against misplacmg or losing the same and the stop is always handy for immediate application to the cable when the occasion arises. Sufficient slack is provided in the chain 12 to enable placing the stop in either of the two positions in which the same is to be used.

As shown particularly in Figs. 2 and 3, the stop 11 comprises a U-shaped sheet metal strap bearing an integral lug or other suit able projection 13 to provide an abutment for the roller 9 when the roller rests on top of the stop with the stop straddling the cable 10 in the manner shown in Fig. 3. It will be seen that the stop is of small enough proportions to be received in the peripheral groove of the sheave roller and permit the latter rolling over and upon the stop. The edge 14 of the stop is tapered, as indicated, to form an easy approach for the roller onto the stop in an obvious manner. If desired, the surface of the stop may be ground off in the vicinity of the projection 13, as shown at 15, to provide a hollow in which the roller 9 will ride when along side of and in engagement with the projection 13. It is obvious that the projection 13 will be situated on that side of the roller toward which the carrier tends to drift. It

either side of the roller. The stop serves as a frictional shoe and positively holds the carrier against drifting out of position. The weight of the carrier, it will be seen, is brought to bear upon the stop thus giving the latter a firm grip on the cable to avoid the likelihood of slipping.

It isbelieved that the foregoing gives a clear-understanding of my invention and while I have illustrated but a single work ing embodiment it should be manifest that changes might be made in details of construction without departing from the spirit and scope of the invention as expressed in the app-ended claims, in which I claim:

1. A cable stop for traveling carriers comprising a U-shaped strap member for straddling the cable with the two arms thereof depending on opposite sides of the cable,

said arms being of ample length and weight to act-as counterweights to hold said strap member always in its proper position, and thebight portion thereof being narrow enough to fit within the peripheral groove of the pulleywheel of the carrier to permit the wheel to rest thereon, and a stop projection on the outside of said bight portion for engagement by said wheel.

2. A cable stop as recited in claim 1 arranged to be reversible end for end relative to said Wheel to be used with said carrier traveling in either direction, and a flexible connection between said strap member and said carrier providing for the free suspension of said member on said carrier when not in use, said connection having suflicient slack therein to enable placing'said mem ber onto said cable on either side of said wheel.

In witness of the foregoing I affix my signature;
